Load on OUT1 has a short-circuit or an overcurrent
has occurred.
Turn off the power supply and
replace the load connected to
OUT1 (black wire).
Load on OUT2 has a short-circuit or an overcurrent
has occurred.
Compared with the ambient pressure, ±0.07 MPa (in
case of 1 MPa use) or ±7 kPa or more (in case of
vacuum use or 100 kPa use) has been applied during
zero clear.
Turn off the power supply and
replace the load connected to

Pressure Setting
∗: The symbol shown in [ ] indicates the pin assignment of the connector.
Peak hold mode
Pressing the button when pressure is displayed enables the
upper limit peak value (value with a high degree of vacuum) to be
held. In this case, "H" is displayed on the LCD. To reset holding,
press the button again.
Bottom hold mode
Pressing the button when pressure is displayed enables the
lower limit peak value (value with low vacuum) to be held. In this
case "d" is displayed on the LCD. To reset holding, press the
button again.
Reset function
Pressing the RE ET button causes the following
1. Measurement mode
•Zero clear
•Clearing the peak hold mode or bottom hold mode
•Clearing the failure predictive function internal counter
•Resetting the failure predictive output
2. Upon error occurrence
•The data set in the setting mode is retained as is and the state when the
power supply was turned on is restored ( ystem reset is triggered).
•In case of a data error, the setting mode is selected. When you finish
setting, the state when the power supply was turned on is restored.
( ystem reset is triggered).
∗: In the set value input mode, the reset function does not work.
Replacement of elements
If element clogging causes deterioration of the
adsorption force or slows the response time,
stop operation and replace the element.

The failure predictive detection counter is incremented when the switch is
turned on then is turned off, without the pressure (exceeding P1) not reaching
the failure predictive pressure (P3).
The failure predictive detection output is energized when the set failure
predictive counter (EC) is incremented consecutively. When the switch is
turned ON and the pressure (exceeding P1) exceeds the failure predictive
pressure (P3), the failure predictive counter is reset.

How to reset the product after a power cut or forcible de-energizing
The setting of the product will be retained as it was before a power cut or de-energizing.
The output condition is also basically recovered to that before a power cut or
de-energizing, but may change depending on the operating environment.
Therefore, check the safety of the whole installation
before operating the product. If the installation is
using accurate control, wait until the product has
warmed up (approximately 20 to 30 minutes).
